MOWER.

SPECIFICATION forming part of Letters Patent No. 447,328, dated March 3, 1891. Application iiled September 18, l890. Serial No. 365,429. (No model.)

T0 all whom it may concern.'

Be it known that I, GUsTAE JEENBERG, a citizen of the United States, residing at Rockford, in the county of innebago and State of Illinois, have invented certain new and useful Improvements in Mowers, of which the following is a specification.

The principal object of my invention is to provlde improved means for raising, lowering, and controlling the finger-bar of a mower by employing a counterbalancing-spring and auxiliary devices in connection therewith.

The minor objects of my invention will be fully stated hereinafter.

This invention consists of certain new and useful features of construction and combinations of parts hereinafter fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, which form a part of this specification, Figure l is a plan View of a mower provided with my improvements. Fig. 2 is a front elevation of the same. Figs. 3, 4, and 5 are side elevations of the mower, fragmental, showing the different operations of the various levers thereof on the finger-bar, the movements of the levers and finger-bar, and the parts connecting and co-operating with them being indicated by dotted lines. Fig. Gis a view in isometric, showing a cam for throwing the machine into and out of gea-r and a latch for locking the cover of the gear-case, both parts being actuated by the same spring. Fig. 7 is a section at the dotted line 7 7 in Fig. 3 of some parts there shown. Figs. A8 and 9 are views in detail of parts shown-in Fig. l, which will be fully described hereinafter.

Like letters of reference indicate corresponding parts throughout the several views.

A A A2 A3 A4 A5 A6 are respectively the A axle, wheels, frame, tongue, hinge-bar, fingerbar, and inner shoe of the mower, and are constructed, arranged, and connected together.

in the usual manner.

B is a rock-shaft, having bearings B in the frame of the mower, and being provided with a counterbalancing-lever B2, projecting upward therefrom, the lower end of said lever having segment-gear B3 thereon.

B4 is a ratchet-wheel integral and concentric with the rock-shaft B.

B5 is an equalizing-pulley arranged to move freely up and down in the recess BG in the counterbalancing-lever B2.

C is a tilting post rigidly connected with the hinge-bar-A4.

C is a segment-pulley, having a groove C2 in its'peripheral portion mounted on the tilting post C between the ends thereof.

Dis a gag-lever, pivotally mounted on the shoe AG at D and controlling the finger-bar A5 in the usual manner.-

E is a chain having axial connection` with the equalizing-pulley B5, passing over a pulley E, mounted on the frame A2 of the mower and the segment-pulley O and connecting with the upper end of the gag-lever D.

F is a ratchet-wheel mounted and revoluble on and concentric with the rock-shaft B, and adapted to engage with its counterpart ratchet-wheel B4.

F' is a counterbalancing-spring coiled about the rock-shaft B, having one end fast to the mower-frame at F2 and the other end inserted into the slotted opening F3 in the periphery of the ratchet-wheel F.

F4 are holes for admittinga pin to wind up the ratchet-wheel F to increase the tension of the spring F.

G is a foot lifting-lever, provided at its lower end with-the counterpart segment-gear G', meshing with the segment-gear B3, and mounted on the pivot-bearing G2on the mowerframe.

H is a hand lifting-lever, mounted on the rock-shaft B and adapted to engage with the lug B7 on the counterbalancing-lever B2 whenever said hand lifting-lever is swung back- .ward far enough to come in contact therewith.

H is a segment-rack rigidly connected with the mower-frame A2.

H2 is a detent connected with the hand lifting lever and adapted to engage with the segment-rack H.

I is a draft-adjusting bar having hook connection at its lower end with the hinge-bar A4, and having its upper end passed through the slot A7 in the mower-frame A2, wherein it may freely slide vertically, as indicated by dotted lines in Figs. 4 and 5.

I is a draft-clevis adapted to slide on the IOC) tongue A3 of the mower, whereto it is connected by means of a retaining-plate I2 and a bolt I3, passed through a slot I1 therein.

I5 is a draft-rod having hook connection with the draft-adjusting bar I and the draftclevis I by means of holes I6 and an eye lT therein. Draft 011 the finger-bar A5 may be increased by lowering and diminished by raising, respectively, the connection between the draft-rod I5 and draft-adjusting bar I, for which adjustment a series of holes I1j therein provides.

J is a segment-rack rigidly connected with the mower-frame A3.

J is a tilting-lever mounted on or near the base of the segment-rack J.

J2 is a detent connected with the tiltinglever J and adapted to engage with the segment-rack J.

J3 is a tilting-rod connecting the lower end of the tilting-lever J with the upper end of the tilting post C.

K is a push-bar composed of two parts K', and connecting the lower portion of the tilting post C with the lower end of the downwardly-extending arm A3, which is integral or rigidly connected with the frame A2 of the mower. rlhe tilting post C has a hole C3 therein of greater diameter than the holes K2 in the push-bar K. The arm A8 also has a hole therein of greater diameter than the holes K2 in the push-bar K.

K3 is a bushing tapering at each end and inserted into the hole C3 in the tilting post C.

K1 is a bolt passed through the holes K2 in the push-bar K and the hole K5 in the bushing K3. The two parts K of the push-bar K are secured to the ends of the bushings K3 by means of the bolt K4 and a nut K3. The connection of the push-bar K with the arms A8 is the same as that just detailed. The construction shown allows the push-bar K free lateral rocking motion, as indicated by dotted lines in Fig. 7, which, taken together with the draft-adjusting bar I, having the connections with the mower-frame A2 and hinge-bar A4, already shown, thereby permits greater freedom to the finger-bar A5 in its vertical movements.

There is a train of gearing such as is ordinarily employed to transmit power from one of the wheels of a mower to the cutter-bar thereof contained in the case and cover A9 A10. L is one part of a clutch integral with the rear wheel L2 of said train of gearing. L is a counterpart thereof adapted to engage therewith and be disengaged therefrom by sliding the same endwise on its shaft L3, as indicated by dotted lines in Fig. 6, to throw the mower into and out of gear.

L4 is a shipping-rod mounted and adapted to slide in a bearing A11 in the part Af.

L5 is a shipper rigidly connected with the inner end of the rod L* and restingloosely in the annular groove L6, located between the part L of the clutch and the longitudinallysliding gear-wheel L7.

L8 is an actuating-spring holding the part L when normal into engagement with t-he part I4.

LJ is a cam provided with a handle L10, connected with the outer end of the rod L4 by means of the pivot L11 and having an operative bearing on the outer end of the part A11.

L12 is a latch capable of horizontal operation, as indicated by dotted lines in Fig. l, loosely connected with the rod L1 by means of a ring L13, encircling the same, and actuated by the spring L3. The latch L12 engages with the slotted lug A12 on the cover A111 to secure the same to the case A1.

Whenever the lever G is operated, the pulley B3 travels downward in said recess B, as indicated by dotted lines in Fig. 5,thus shortening the short arm of said lever G as the finger-bar is raised, and thereby equalizing the power required to raise said nger-bar from the ground to its upper limit.

The wheels A next to the observer are removed in Figs. 3, 4f, and 5. The levers II J are also removed in Fig. 5.

The tension of the spring F may be increased in the manner already stated until it will partially, nearly, or quite counterbalance t-he weight of the finger-bar A5 and the parts supported thereby, according as may be desired.

Whenever it is desired to partially raise Vthe finger-bar to pass obstructions or turn corners in mowing, the operator will press his foot on the foot lifting-lever G. If, however, it is desired to raise the finger-bar to its upper limit, the operator will press the hand lifting-lever I-I to supplement the work of the foot lifting-lever.

The linger-bar may be tilted backward and forward by means of the tilting-lever J', as indicated by dotted lines in Fig. 3.
